Liverpool police will test their strength against teams from the Australian Defence Force, other commands and organisations at Richmond Air Base this weekend. As a fund-raiser for the NSW Special Olympics team, they will battle to see which group can pull a plane over a set distance in the quickest time. Organisations interested in sponsoring the Liverpool team can call Chief Inspector Guy Haberley or Inspector Paul Smith on 9821 8444.

Mortar shell found

Military police and the Australian Federal Police were called to an excavation site within Holsworthy Army Barracks on Monday, after workers found a three-inch mortar shell partially buried in the ground. Police evacuated the site, near Heathcote Road, and specialists officers were called in to detonate the device. All traffic, including rail, was stopped during the incident as a precaution.

Driving offences

A 20-year-old Moorebank man was charged with driving offences after he allegedly led police on a short chase through Chipping Norton on Saturday night. Police said the man, who was driving a red Honda Civic threw an object at the officers as they approached the car and sped off. It was alleged he reached speeds of 90km/h in a 50km/h area. The chase ended when the driver wedged his car between bollards in parkland off Rickard Road. He tried to fight the officers as they attempted to arrest him. During the struggle, a passenger from the vehicle, a 20-year-old Punchbowl woman joined in and was also arrested. The man was charged with driving an unregistered vehicle with stolen number plates and while disqualified. He also had a small quantity of ice, police said. He will appear in Liverpool Court on September 9.
